Hi, I'm attempting to work on this issue and have linked a draft PR. I have added the --zero option and implemented the nul/newline by changing the instances of println!...

Changed to use `LineEnding`. As a general question, is there a good way to know if a needed code function is found in uucore and what is not?

Thanks @dchenbecker for the insights! I'm not sure about looking at the GNU coreutils source code. But at least according to the `info cksum` and just running the GNU coreutils...

Please assign me to this issue. I have already almost finished the implementation of the solution. Thank you

Unfortunately, school got busy and had to put this aside temporarily. Will be back on this in 1 week.

@RenjiSann thanks for reminding me haha, I unfortunately don't have time so I will close this PR. Feel free to have a go at it
